Altimeter: GPS Elevation

See exactly how high you are. AltiMeter reads your live altitude, barometric pressure and oxygen level straight from your iPhone's built-in barometer and GPS — an instant, accurate elevation gauge in your pocket. Most altitude apps stop at a single number. AltiMeter turns your phone into a full climb companion: record a hike or ascent, watch your gain and peak build in real time, then review the elevation profile of every trip. And because the barometric sensor needs no signal, your altitude keeps reading even deep in the hills with no mobile service. WHAT YOU GET - Live altitude from GPS and the built-in barometer, updated as you move - Real-time air pressure in hPa or kPa with a plain-language conditions band: Low, Below average, Normal or High - Oxygen level estimate so you can gauge thin air at high elevation - Record any climb and capture gain, peak, ascent, descent, range and duration - Elevation profile chart for every session, saved to browse any time - Session history with your total tracks, highest point and total ascent - Compare your height to Ben Nevis, Mont Blanc, Matterhorn, Everest, K2 and more famous peaks - Atmosphere reference chart: pressure and oxygen at every elevation band, metres or feet PERFECT FOR - Hillwalkers and mountaineers tracking elevation on the trail - Cyclists and fell runners logging total ascent - Drone pilots and skiers checking altitude before take-off or a run - Anyone curious how high their town, hotel or favourite lookout really sits WHY NOT JUST CHECK THE BUILT-IN COMPASS? The Compass app shows one static altitude and nothing else. AltiMeter reads live pressure, estimates oxygen, records your whole climb as a chart you can revisit and share as text, and works offline through the barometer when GPS drops out. PRIVACY Every reading stays on your device. No account, no adverts, no tracking. A daily reminder keeps you in the habit of checking in. FULL ACCESS AltiMeter is free to see your live altitude, pressure and oxygen, and to save up to three sessions. Go Premium to record unlimited climbs, keep your full session history and detailed session view, and export any track as text to share or log. Premium is offered as a weekly or yearly subscription, or a one-time lifetime purchase, unlocking every feature the moment you upgrade.
